DCP200 Profile Controller & Recorder - Product Manual

Recalibration Procedure

Recalibration is carried out in five phases as shown in the table below; each phase corresponds to a basic input type.

CAUTION:

The 50mV phase MUST be calibrated before the thermocouple range.

Table 27. Input Calibration phases

DC milli-volt Calibration

50 mV

DC voltage Calibration

10 V

DC milliamps Calibration

20 mA

RTD Calibration

200 ohm

Thermocouple Calibration

K type source at 0ºC

1.For optimum accuracy, power-up the instrument for 30 minutes, then toggle the power off/on to restart the instrument.

2.During the power-up “splash screen”, press and together until the Calibration Status screen is displayed.

3.Press to select the first calibration phase (50mV Calibration)

4.Ensure that an accurate 50mV signal has been applied to terminals 2 (+ve) and 3 (-ve), then press + to initiate the calibration.

5.During calibration the message “50mV DC Input Calibrating” will display for a few seconds. This should be followed by the “Calibration Successful” confirmation.

6.If the input is misconnected or an incorrect signal is applied, the calibration will be aborted and the display will show “Failed: Signal Too Small!” or “Failed: Signal Too Large!”.

The previous calibration value will be retained.

7.Press to select the next calibration phase.

8.Repeat this process for each input type until all the phases are calibrated. For each phase, ensure that the correct input is applied, using the correct connections.

9.Once all calibration phases are completed, recorder versions will display the Calibration Reminder Date. If required, this can be changed to the date of your next calibration check. Ensure that Calibration Reminders are enabled in Input Configuration to receive a reminder.

10.Press + to exit to the main menu.

Note:

Calibration Mode automatically exits if there is no button activity for two minutes.
